 it did. You couldn't have used it if it wasn't working:-). It doesn't
 mean it's not failed since then (and inded that the seller hasn't tried
 it, found it doesnt; work and is thuse selling it). 
You know it is possible for
something to work, but not to its full
capability, right?
The computer that I am typing this message on has a non-functioning
DVD drive and occasionally the keyboard and touchpad just stop working.
I would not describe it as 'worked fine the last time I used it'.  Yet
it works
well enough that I can use it for lots of tasks.
To the original poster, I agree that you probably didn't emphasize the 'for
parts' aspect enough.  I buy and sell a bunch of stuff online and one thing
that I learned is that buyers often do not read things closely.
